I have a friend that gave the thumbs up for the flytech. He use the it and seems to be satisfied with it.
I thinknthe flytech can be used with both DC or AC. Or maybe i am confused?
That's the Vape that is AC or DC. The flytech is basically the same as Vepspatronic, Malossi etc ignition, but has a number of parts that are not interchangeable. It'll work, just the Vape is much better.

Ah, yeah, I bought some different sealments. I have one in silicone, that will work perfect for the bolts.

Very god tips about the carburator. I will look into the dellorto. As you, have a product that are used by many will make it easy to get fast and proper suggestions.

I have read that some use reed valve, even though I will have original rotary valve.
What are your thoughts about that?
Not something you would do when you have a good rotary seal. Leave that for the next motor.

I will look into carb and intake and see what I find. Maybe I just go for the the SIP 3 exhaust.
I have also only heard good things about it.

Good tip about the seal for rhe clutch. Is that seal known to get worn out faster maybe?
No, don't think so. Charlieman22 has installed one on his. I don't like that manifold personally for the reasons I mentioned earlier. Other options are -

Hello guys!

Business as usuall with life and not very much time for the vespa...
Have had som issues with the engine process, however Ginchi have helped me out, a lot! 😊

My reinforced plate for the case was not very well placed. It was welded to high and as result the inputshaft was to close. Had to cut the plate and use a hammer to punch it down a bit. Needs to get some new weld job done...

Anyway... the gearbox is good to go and the input shaft is renovated.

Dry bulit the engine with dummys today And it seems fine with everything, except the crankshaft.
I have a new crankshaft that is not the same width regarding to the original (new one: 39,88mm, old one: 40,24)

This gives me a lot more axial differnce. Measured it to about 0,65mm. Not sure what the tolerance is?
See video here:

Cheers!

So I am still having some problems with building the engine.

It is quite a mess to be honest. If I would knew that there would all thoes obstacles, I would definietly bought a newer case from the beginning 😅.

Anyway. Next issue os as follows.

I bought SIP's oil seal kit from DRT. The kit is made to let you change the oilseal without having to split the case.

However this kits demands some shims, since you lose the flange that measures about 1mm and will mess up the tolerance in the axial space for the crankshaft.

However the problem with the shims is that you block the oil channel.

Is there anyone that have any solution for this?
Please see pictures.

Pictures shows as following:
Pic 1: splitted case, flywheel side with original oil seal.
Pic 2: splitted case, flywheel side with the DRT oil seal, for comparing.
Pic 3: splitted case, flywheel side, with oil channel and mounted oil seal.
Pic 4: splitted case, flywheel side with the shims that are needed for the loss of tolerance.

Thanks in advance 😊

I ran Flytech's before the Vape came out. If I was lucky, the CDI would last six months on a daily rider.

Once the Vape came out, I switched over and never looked back.
